The angiographic photos of the lower extremity artery were observed and studied. The perforating vessels of the lower abdominal artery and the anastomosis between the anterior and posterior cavities of the artery were analyzed, which provided the image basis for the design and clinical application of the perforated foot flap. Methods: the imaging results of patients with arteriography of lower extremity were collected retrospectively. To observe the travel, distribution and connection between the perforating vessels of anterior tibia, posterior tibia and peroneal branch of peroneal artery. The skin and soft tissue defects of the leg and leg were repaired by the perforator flap of the leg artery, anterior tibial artery and posterior tibial artery. Results: the perforating vessels of fibular artery, anterior tibial artery and posterior tibial artery were found to branch on the skin during walking to the skin. The direct anastomosis of clavicle like blood vessels can make the blood flow "channel" of skin have a clear direction. The area of the perforating branches of the posterior tibial artery and the fibular artery exceeded the blood supply of the two unrestricted areas without blood flow disturbance. Conclusion: angiogram can clearly show the shape and direction of perforating vessels and the connection between adjacent perforating vessels.
